Yintoni i-LED Dimmer Driver?

Ekubeni ii-LED zifuna umbane othe ngqo kunye nombane ophantsi ukuze zisebenze, umqhubi we-LED kufuneka alungiswe ukuze alawule ubungakanani bombane ongena kwi-LED.
Umqhubi we-LED yinxalenye yombane elawula i-voltage kunye nomsinga ovela kumbane ukuze ii-LED zisebenze ngokukhuselekileyo nangokufanelekileyo. Umqhubi we-LED utshintsha umbane otshintshanayo (AC) ukusuka kumbane oyintloko ukuya kumbane ongqongqo (DC) kuba uninzi lwezixhobo zamandla zisebenza kumbane oyintloko.
I-LED ingenziwa ifiphale ngokutshintsha i-LED driver, ejongene nokulawula ubungakanani bombane ongenayo kwi-LED. Le driver ye-LED eyenzelwe wena, ngamanye amaxesha ebizwa ngokuba yi-LED dimmer driver, itshintsha ukukhanya kwe-LED.
Kubalulekile ukuqwalasela indlela elula yokusebenzisa i-LED dimmer driver xa uthenga enye. I-LED dimmer driver ene-dual in-line package (DIP) switches ngaphambili yenza kube lula kubasebenzisi ukutshintsha i-output current, nto leyo etshintsha ukukhanya kwe-LED.
Ukuhambelana kwe-LED dimmer driver kunye neepleyiti zodonga zeTriode for Alternating Current (TRIAC) kunye nombane yenye into ekufuneka uyijonge. Oku kuqinisekisa ukuba ungayilawula indlela umbane ohamba ngesantya esiphezulu ongena ngayo kwi-LED kwaye i-dimmer yakho iya kusebenza kuyo nayiphi na iprojekthi ocinga ngayo.

Iindlela ezimbini okanye ulungiselelo lusetyenziswa ngabaqhubi be-LED dimmer ukulawula umsinga wombane ongena kwi-LED: i-amplitude modulation kunye ne-pulse width modulation.

Ukunciphisa ubungakanani bombane ohamba phambili odlula kwi-LED yinjongo ye-pulse width modulation, okanye i-PWM.
Umqhubi uvula aze avale umbane aze awuvule kwakhona rhoqo ukuze alawule ubungakanani bombane onika amandla i-LED, nokuba umbane ongena kwi-LED uhlala ungaguquki. Ngenxa yolu tshintshiselwano lufutshane kakhulu, ukukhanya kuyafiphala kwaye kukhanye ngokukhawuleza kakhulu ukuba umntu angakuboni.

Ukunciphisa ubungakanani bombane ohamba kwi-LED kwaziwa ngokuba yi-amplitude modulation, okanye i-AM. Ukukhanya kwe-dimmer kubangelwa kukusebenzisa amandla amancinci. Ngendlela efanayo, ukwehla kombane kubangela ukuba amaqondo obushushu aphantsi kwaye ukusebenza kakuhle kwe-LED kunyuke. I-Flicker nayo iyasuswa ngale ndlela.
Nangona kunjalo, khumbula ukuba ukusebenzisa le ndlela yokufiphalisa ukukhanya kunengozi yokutshintsha umbala we-LED, ingakumbi kumanqanaba aphantsi.

Ukufumana abaqhubi be-LED abanokufiphala kuya kukunceda ufumane okuninzi kwizibane zakho ze-LED. Sebenzisa inkululeko yokutshintsha amanqanaba okukhanya kwee-LED zakho ukuze wonge amandla kwaye ube nokukhanya okukhululekileyo endlwini yakho.
